This specification establishes the engineering requirements for producing an acid-type, anodic coating on magnesium alloys and the properties of the coating.
1.1 This guide covers sampling for prebaked carbon anodes used in the production of aluminum, and details procedures for taking test samples from anode blocks. It covers equipment and procedures for obtaining samples from anode blocks in a manner that does not destroy the block...
1.1 This test method is intended to determine whether anodic oxide coatings on aluminum and its alloys, that have undergone a sealing treatment and contact with an acid solution, are stainproof or nonadsorptive with respect to dyes. 1.2 Coatings that have been properly sealed should be proof...
Automotive parts can be fabricated from either coiled sheet, flat sheet or extruded shapes. Alloy selection is governed by finish requirements, forming characteristics, and mechanical properties. Bright anodizing alloys 5657 and 5252 2x sheet provide a high luster and are preferred for trim...
1.1 This specification covers the requirements for zinc anodes in the form of slabs, plates, discs, and rods for corrosion protection (cathodic protection) of metals and alloys. 1.2 The anodes are primarily intended to reduce corrosion of surface ship and submarine hulls, steel and...
1.1 These test methods cover the determination of acid and base milliequivalent contents of anodic and cathodic electrocoat baths and their ultrafiltrates. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This...
1.1 This specification covers requirements for electrolytically formed oxide coatings on magnesium and magnesium alloy parts where appearance, abrasion resistance, and protection against corrosion are important. 1.2 This standard does not purport to address all of the safety concerns, if any,...
3.1 This test method can be utilized to verify the performance of polarization resistance measurement equipment including reference electrodes, electrochemical cells, potentiost- ats, scan generators, and measuring and recording devices. The test method is also useful for training operators in...
1.1 This test method covers the determination of the thickness of metallic coatings by the coulometric method, also known as the anodic solution or electrochemical stripping method. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It...
This practice describes the photomultiplier properties that are essential to their judicious selection and use of in emission and absorption spectrometry. The properties covered here include structural features, electrical properties, and characteristics involved in precautions and problems. The...
This specification establishes the engineering requirements for producing anodic coatings on magnesium and magnesium alloys, from an alkaline electrolyte, and the properties of those coatings.
5.1 This test is a guide for evaluating magnesium anodes. The degree of correlation between this test and service performance has not been fully determined. 5.2 Test specimens from the same casting may not be identical because of inhomogeneities in the casting. A method of ensuring that...
5.1 Hard anodic oxidation coatings are often used to obtain improved resistance to abrasion, and have been used in such applications as valves, sliding parts, hinge mechanisms, cams, gears, swivel joints, pistons, insulation plates, blast shields, etc. 5.2 This abrasion resistance test...
5.1 This technique is applicable to dry paint films and varnishes in a variety of forms including the intact dry paint film surface, a notched or other angular cut surface that exposes a cross section of all paint layers, a paint chip, and ground paint film. 5.2 The response of the spot test method...
This specification establishes the requirements for a hard anodic coating on aluminum and aluminum alloys.
1.1 This specification covers high-silicon cast iron castings intended for corrosion-resistant service. 1.2 This specification covers three grades as shown in Table 1. Selection of grade depends on the corrosive service to be experienced by the casting. All three grades are suited for application...
1.1 This practice covers a preferred method for evaluating the condition of electroplated test panels that have been exposed to corrosive environments for test purposes. It is based on experience in use of the method with standard 10- by 15-cm (4- by 6-in.) panels exposed on standard ASTM racks at...
This specification covers the materials, dimensions, inscription, and methods of inscribing for shipboard valve label plates. Label plates shall be classified by type, grade, class, size, and letter size in accordance with material and method of inscribing, method of attachment, thickness of sheet,...
5.1 The grain stability of calcined petroleum coke determines the resistance to breakdown of + 4?mm particles used in the manufacture of carbon anodes for use in the reduction process of aluminum. 5.2 Calcined petroleum cokes have to be relatively easy to grind for fines production but...
This specification establishes the procedures used to produce a hard anodic coating on magnesium alloys and the properties of the coating.
